But after all, to be in the open was infinitely better than to be eating his heart out in a squalid prison camp. His health stood less chance of being undermined. As to the shells, he had grown so used to that form of danger that it hardly disturbed him at all.

But the one thing that stood out above all others was that in the woods he would have a chance of escape, while in the camp he would have practically none at all. His limbs would have to be free in order to do the work demanded of him. And he was willing to match his keen American wits against the heavy and slow-thinking guards who might stand watch over him.

He soon reached the section where he was to work, and was set to felling trees to make corduroy roads over which guns and supplies could be brought up from the enemy's rear to the advanced lines.

He had never done that kind of work, and at first the tremendous efforts demanded of him amounted to sheer physical torture. He was hounded on unceasingly under the jibes and threats of his brutal guards. Not half enough food was supplied, and he was forced to work for sixteen and eighteen hours on a stretch.

But he had great reserves of youth and vitality to draw on, and he kept on doggedly, his brain alert, his eyes wide open, his heart courageous, looking for his opportunity.

On the third night his opportunity came.
